JOYCE v2.2.7 (stable) released. This contains code to guard against the
possibility of a malicious CP/M program overwriting or deleting important
files on the host computer or crashing JOYCE. If you use JOYCE / ANNE to run
CP/M programs downloaded from the Internet, I recommend that you upgrade to
this version.

PCW television output

This is a circuit diagram for a PCW-to-television converter,
allowing a PCW screen to be displayed on one or more television
sets. I redrew it from the original, published in the Crawley PCW
Club magazine.

PCW / PC Hybrid

This advertisement is for a "Swift-286-PCW", a hybrid between a 286 PC
and a PCW. Apparently only fourteen of these were ever sold, so the chances
of one still existing must be pretty slim.

Though I've not seen one, I'd guess that the PCW compatible video card
was a monochrome card (probably MDA or Hercules). The PCW video system has a
command ('float video' - OUT 0xF8, 8) which stops the PCW video controller
trying to drive the monitor. The monitor signals are present on the PCW
expansion port (pin 44 for SYNC, 46 for VIDEO) so once the PCW video
controller has been disabled, the PC video card can drive the monitor using
them.

My thanks to David Rathbone, who owned Micro Surgeons, for information on
this system.
